The present invention has relation to pipe machines, and it consists in the different parts and combination. of parts hereinafter described and mrl.imll:u'l v pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, 1 represents the base of the machine, which is formed of a length to correspond substantially with the length of the machine proper. The frame 1 should be of rigid construction and of suflicient strength to support the various parts of the machine, which parts are connected and arranged substantially as hereinafter described. The base which isto be supported in proper elevation by means of the legs 2. To the base 1 are securely attached the housings 3 and 4, which housings are for the purpose of providing a means for carrying the various shafts hereinafter described, which shafts are located or journaled in suitable bearings. In the rear pair of housings 3 and 4 is journaled the power shaft 5, which power shaft is provided'with the usual tight and loose pulleys 6 and 7.

It will be understood that it is not absolutely necess 'sary to journal the shaft in the housings as above described, but it may be journaled in a separate structure,

and the, same object and purpose carried out.

The power shaft is provided with the driving pinion 8, which driving pinion meshes with the gear wheel 9, which gear wheel is securely mounted upon the shaft 10. The gear wheel 9 meshes with the gear wheel 11, which gear wheel is mounted upon the shaft 12, and upon the shafts and 12 are located the delivery rolls 14. Directly in front of the shafts 10 and 12 are located the shafts and 16 and upon the shaft 16 is securely mounted the gear wheel 17. Upon the shaft 15 is mounted the grip wheel or roll 18, and upon the shaft 16 is mounted the combined grip and ('orrugating wheel or roll 19, which rolls are located directly one above the other. Directly in front of the shafts 15 and 16 are located the shafts 20, and 21, and upon the shaft is mounted the seaming roll 22, and upon the shaft 21 is mounted the grip roll 23, said rolls being located one above the other as illustrated in Fig. 4.

It will be understood that the upper series of shafts should rotate in the same direction and the lower series of shafts should rotate in the same direction, but the upper series of shafts must rotate in the opposite direction from that of the lower series and in order to provide for this movement the idlers 24 and are interposed between the lower set or system of gear wheels, which idlers are loosely n'iounted upon short studs 26 or their equivalents. Between the upper series of rolls and thelower series of rolls above described is located the mandrel 27, which mandrel is supported by the lower :series of rolls. The mandrel 27 isprovided with the integral eorrugatml portion 28, which integral eorlugated portion is for the purpose of assisting in forming the corrugations in the pipe in conjunctionwith the combinedgrip and comigating roll 19, and the radial corrugating, rolls 29, whichcorrugating rolls 29 are properly journaled in. the adjustable plates 30 which'adjustable plates are held by means of theshaits 15 and 16. For the purpose of holding the corrugating rolls 29 in proper position the detachable plates 31 are provided,. which detachable plates are connected, to the plates 30 by means of suitable screws 32 or their equivalents. i

For the purpose of holding the plates 30 in proper relative position with the shafts 15 and 16, the top or upper portion of the plates 30 are bifurcated, which bifurcated portions receive the upper shaft 15.. i The lower endof the plates are held in proper position by means of the clip 33, which clip or connected by means of the screws 34 or their equivalents. I To compensate for different thicknessesoi metal employed in the manufacture of conductor pipe, and also to provide for the l'ormation of deepand shallow corrugations the plates 30 together with the different'parts carried thereby are adjustably mounted upon the shafts 15 and 16 and are 'held in fixed adjustment against outward movement by the .set screws 35, .which set screws are adjustable with reference to the plates 30, and by changing the adjustment of the set screws 35, the plates 30 together with the parts carried thereby are set to or from the mandrel 27, by which arrangement I am enabled to providefor different thicknesses of metal. For the purpose of providing adjustment between the periphcries of the rolls 18 and 19 the upper shaft 15 upon which the roll 13 is mounted is located in the adjustable bearcorrugated the anti-friction rolls 37 and 38 are provided,

ings 36. v

For the purpose of reducing the friction as between the pipe and the mandrel during the time it is being 27 is attached the bar 40, which bar is formed of suflicient length to receive thereon the skelp from which upright 41, .which upright is secured by bolts or other wise to the bed plate 1. Directly below the bar 40 is located a movable bar 42, which movable bar is supbars extend downward through the bed-plate 1 and their bottom or lower ends connected to the foot levers 44,-:which foot levers are mounted upon the rod 4501' its equivalent, and the rod held in fixed position by means of the brackets 46, which brackets are connectedto the bed-.platel or its equivalent. To the'bar 42 are attached the outwardly bent short bars 47, which bars constitute compressors for the skelp designed to be corrugated, and iru use" the skelp before the hooked edges thereof are connected together is placed upon the .bar 42 and is permitted to hang upon said bar. .While the skelp is in this position the foot levers 44 are the pipe is to be made. The bar 40 is connected to the ported by meansof the vertical bars-43, which vertical wardly bent bars '47 may be employed.

-ji lt will be understood that pressed downward at their outer ends or one of theioot levers pressed downward, as the case may be, wlii elevates the inner ends of the foot levers and move t bar 43 upward, and by reason'of the angled bars 47 cated above the bar 42 the pipe or skelp when brough in contact with the bottom or under edge of the bar 40,,

will have atendency to compress the pipe and bring the hooked edges in proper position to be hooked together. It will be understood that any desired number of out- Aiter the hooked edges of. the skelp have been properly connected together the bar 42 is lowered so 918 to permit the skelp to hang iipon thebarhO, and th pipe is then moved endwise until it is gripped between the seaming roll 22 and the roll 23 and the antirfriction rolls 48-, and by the rotary movement of the seaming roll 22 and the roll 23 the pipe is then moved. over and upon the mandrel and as the pipe advances it will be gripped between the rolls 18 and wand the anti-friction rolls 37 and 38 and at this point the mandrel is corrugated and the corrugations pressed into the pipeas it passes the corrugating rolls 29, thuscompleting the corrugations oi the skelp. 1

It will be understood that the pipe must 'move in a true line and for the purpose of preventing any. twisting or turning of the pipe the bar 42 is provided with the flange 49 upon which flange the outer edge or face of the lower hooked edge of the pipe abuts.

For the purpose of holding the hooked edges of the A pipe in proper engagement with each other, and at the same'time guiding the pipe in a true line the. bar 50 is provided; which bar is connected to the adjustable sup port 51, which adjustable support is connected to the bed-plate 1 or its equivalent.

, the flanges 49 and the flahge bar 50 are so arranged that" they will hold the hooked edges of the skelp together and at the same time guide theskelp in such a manner, that when the skelp reaches theseaming roll 22 the'hooked edges will be compressed and the seam formed.

For the purpose of delivering the pipe after it has been finished the delivery rolls l4 are'provided. it

will be understood that during the time the skelp is being seamed and corrugated there will be more or less pull upon the mandrel and also upon the bar 40, which is connected to the inandrel and in order to compensate for this strain and prevent any springing of the upright 41 the brace rod 52 is provided, which brace vrodiis connected to the l'owerend ofthe' upright 41, and to some fixed part of the bed plate 1..

For the purpose of manufacturing conductor pipe which is. square in cross-section the round mandrel 27 is removed and the square mandrel 53 substituted and at the point where the seaming is done, the seaming roll 54 is substituted for the seaming roll 22,-which seaming roll is a combined seaming and vcorrugating roll. Below the mandrel 53 is locatedthe corrugating roll 55, which is substituted for the roll 23 and the anti-friction rolls 56 provided. At the point where the pipe is corrugated upon its sides'the corrugating rolls 57 are provided and are journaled in the plates 58, which are supported by th'e shafts 15 and 16. At the point where the corrugating rolls 57 are located the mandrel is providedwith the combined antition and corrugating rolls 59, which are located in the mandrel substantially as shown in Fig. 14. When square pipe is produced the square mandrel is extended or formed somewhat longer than the round one, and the second set dfcorrugating rolls substituted for the delivery rolls l4, and the combined anti-friction and corrugating rails 61 provided.

For the purpose of holding the various shafts upon which the grip, seaming, corrugating and delivery rolls are located said shafts are provided with the detachable collar or flange 62 but are held against the outer faces of the housings and bearings as the case 'may be, by means (if the lug bolts 63 or their equivalents and the hubs 64 or their equivalents.

It will be understood that it is necessary to change from time to time the various rolls reference being had to the class of work they are to perform, and in order to change the rolls the various shafts upon which they are mounted must be'removedfir partially removed and moved endwise and at this time the collar or flange 63 is removed so that the shafts can be moved endwise.

For the purpose of holding the various rolls in proper position the collars 65 and 66 are provided, and the collar 65 held in fixed position in any convenient and well known manner and the collar 66 held by the set screw 67' or its equivalent.

For the purpose of causing the various rolls to rotote with the shafts the keys or feathers 68 are provided, which are seated in suitable grooves formed in theshaft apertures of the various rolls, this feature being best illustrated in Figs. 2 and, 26.

When it is desired to manufacture square and angular pipe the bar 40 should be provided with the pipe holding brackets 69, which are illustrated in Figs. 18 and 19.
